Winner: Catch Bottle Caps With Magnets

Sometimes, the simple hacks are the best and this week's winner shows us something that almost anyone can make use of right away. Jmbarbera mounted the magnet from an old hard drive (a great source of strong magnets) under a wall-mounted bottle opener. It's surprisingly effective, catching the bottle cap every time. No longer will that stray bottle cap get away from you, hiding face up and waiting for your bare feet.

Honorable Mentions

We got a lot of great entries and we'd be remiss if we didn't share some of our favorites. Here are some of the entries that really impressed us.

Keep Your Dryer Door Open

Like many of us, Steve had a dryer door that would start to swing closed whenever he and his family loaded clothes. Fed up with that bit of irritation, Steve decided to solve the problem Lifehacker-style. He cut a small piece out of the drywall and mounted a magnet inside the wall. He patched the hole, covered it up with a little spackle and paint, and now the door stays open whenever it touches the wall. If your door just doesn't want to stay open, the first thing to check is whether the dryer is level—most have adjustable feet. But if that doesn't solve your problem, Steve's hack may be just the thing you're looking for.

Stick Your Smartphone Anywhere With This Magnetic Case Hack

Stone-D likes sticking his iPhone 5 to things, so he fitted neodymium magnets to his Moshi case. His photo does most of the talking, but he can now stick his phone to pretty much any metal surface like his fridge or monitor. As a bonus, he can use the magnets to mount a jeweler's loupe to the case for macro photography.

Save Space While Organizing Your Makeup

Elizabeth lives in a small house where storage is at a premium. She wanted a way to organize her makeup, make it easily accessible, and save space while doing it. Her solution? She painted a piece of sheet metal and mounted it to the back of her closet door. Elizabeth then glued magnets to the backs of her various makeup pots and slapped them right on her new metal board. Problem solved. You can read more about how Elizabeth put this together on her blog.

Create a Periodic Table of Spices

Tyler wanted a creative way to display his spices. Sure, people have long been using magnetic spice racks, but being an engineer and an Alton Brown fan, Tyler wanted to follow the notion of cooking as chemistry. After spending some time on Wikipedia researching taxonomy, he decided to create a periodic table that grouped his herbs and spices by Order and also included the Family, Genus, Species, and English names. He also created the symbols used on the tins. The end result provides out-of-the-way storage and it's a thing of beauty. Tyler has created an instructable where you can learn more about he made it.
